STEPHEN,
YOU REPLACED EVERYTHING BUT THE STEEL LINES...IT'S NOT IMPOSSIBLE 
[THOUGH UNLIKELY] FOR A LINE [STEEL OR FLEX] TO HAVE A 
DEFECT/OBSTRUCTION INSIDE THAT WORKS LIKE A FLAPPER VALVE THAT 
RESTRICTS PRESSURE DURING APPLICATION BUT WILL ALLOW ENOUGH PRESSURE 
INCREASE TO STOP A ROTATING WHEEL WHEN IT IS UNLOADED AND SPINNING OFF 
THE GROUND...THEN WHEN THE PEDAL IS RELEASED THE FLAPPER MOVES ENOUGH 
TO ALLOW THE FLUID PRESSURE TO DROP AND THE BRAKE TO RELEASE. YOUR 
STEEL LINES ARE LIKELY 40 YRS OLD AND WHO KNOWS WHAT'S INSIDE THEM.
IF ALL PARTS ARE NEW [INCL STEEL LINES] AND THE PROBLEM STILL EXISTS BE 
SURE YOU DIDN'T LET THE FRONT HOSES SUPPORT THE WEIGHT OF THE BRAKE 
ASSY [LIKE MOST THINK IS OK WHEN WORKING ON CALIPERS] BECAUSE THAT CAN 
DAMAGE THE INSIDE OF THE HOSE AND EVEN CREATE A FLAPPER VALVE IN A NEW 
HOSE [AGAIN UNLIKELY BUT POSSIBLE]. BTW, STD BRAKE FLUID IS HYGROSCOPIC 
[READILY ABSORBS MOISTURE FROM THE ATMOSPHERE] WHICH IS THE CAUSE OF 
THE RUST INSIDE THE SYSTEM, INCL THE STEEL LINES. [CAST IRON CYL ARE 
POROUS ENOUGH FOR WATER VAPOR TO BE ATTRACTED TO THE FLUID INSIDE BUT 
NOT POROUS ENOUGH TO ALLOW THE FLUID TO LEAK OUT].
GOOD LUCK AND HAVE A GREAT AMERICAN DAY!

I have a '65 Corsa coupe.  I did a complete brake job as soon as I 
purchased
the car.  I replaced the following: brake shoes, wheel cylinders, 
hardware kit
and rubber hoses.  I also had the drums turned and bled the system.  
All of
the metal lines appeared to be in excellent condition.  Test drive: 
Great rear
brakes; No noticable front brakes.  I put car on jack stands, spun each 
tire
by hand and had helper apply brakes.  Each wheel stopped with similar 
pressure
to brake pedal.  I then had a friend who is well versed in drum brakes 
remove
everything that I installed, inspect all parts and reassemble and bleed 
the
system.  No improvement.  Next, we tightened the front self-adjusters 
until we
couldn't turn the drums by hand.  Test drove: still no front brakes.  
Then we
disconnected the rubber hoses (one at a time) to make sure that we were 
getting
a good shot of brake fluid through the hose and bled again.  Still no 
front
brakes!  After many inspections and brake bleedings, I installed a dual
resevoir MC.  WOW!  I now have "some" front brakes, but the rear still 
locks up with
a quick stab of the brakes and the rear squats heavily when braking.  
Any
helpful advice that would give me great drum brakes would greatly be 
appreciated.
